Cosine is one of the three part for trigonometry. 

You have sin, cos, and tan. 

You can easily do this by understanding SOH CAH TOA. 

Sin = OPPO. over HYPOTENUSE
Cos = ADJACENT over HYPOTENUSE
Tan = OPPO. over ADJACENT 

I hope this helps!

Cosine is \frac{adjacent}{hypotenuse} which applies to a right triangle. I hope that helps you.

Can a -150/10 be classified as both a rational number and a integer
irakobra [83]
Yes! This is because -150/10 can be simplified to be -15, which is a rational number.

The word “rational” sounds like another math word you’ve heard of before. Do you know what it is?

Well, it’s “ratio”!! Ratios can be seen in the forms x:y and x/y.


ANY RATIONAL NUMBER HAS THE ABILITY TO BE WRITTEN AS A RATIO!! This will completely exclude numbers with super long decimal points (ex: 1.2345678809928374737272828...)

This number also meets the requirements of being an integer. An integer is any whole number (this excludes decimals and fractions)

I know it’s written as a fraction. However, the fraction could be simplified, making it -15, which means this is both a rational number and an integer!!
